Figure S1.Box plot of six gene expression patterns inferred from the HaCaT gene expression data
for each of the three CoGAPS simulations (pages 1–3) for the samples in Table 1. Plotted values are normalized to sum to one across all samples. All results for
HaCaT-EGFRWT are colored in green, HaCaT-HRASVal12D in red, HaCaT-EGFRWT in grey, HaCaT-p65WT in blue, and HaCaT-vector in black. The y-axis is labeled according to the row of
the inferred P matrix plotted in each panel. Specifically, (a) contains the pattern attributed to
the baseline HaCaT activity, (b) attributed to HaCaT-HRASVal12D, (c) HaCaT-vector, (d) HaCaT-EGFRWT, (e) serum, and (f) HaCaT-p65WT.
